在全球精准肿瘤治疗赛道上，抗体偶联药物（ADC）正与小分子药物擦出新的火花。近日，美国精准 肿瘤公司 IDEAYA Biosciences 在成立十周年研发日上，集中展示了多项研发成果与管线规划，特别引 人注目的是两项来自中国的引进项目：恒瑞医药的 DLL3 靶向 ADC，以及百奥赛图授权的 B7-H3/PTK7 双特异性抗体偶联药物（bsADC）。 这一动作不仅凸显出 ADC 热潮下的国际分工，也让"ADC+小分子"这一新兴组合策略成为资本市场和 行业的焦点。 "小分子+ADC"的组合逻辑 IDEAYA 长期专注 DNA 损伤修复（DDR）通路的小分子药物研发，其首个进入临床的 PARG 抑制剂正 是合成致死策略的代表。然而，小分子药物疗效在单用时往往受到耐药等因素制约。IDEAYA 研发日披 露的数据提示，DDR 抑制剂与 ADC 联合有望产生更强的肿瘤杀伤效果，这也是公司斥资近30亿元引进 百奥赛图双抗 ADC 的核心逻辑。 在临床层面，已有案例为这一思路提供验证。HER2 阳性乳腺癌研究显示，T-DM1（ADC）联合 PI3K 抑制剂阿培利司，总缓解率较单药提高近一倍，中位无进展生存期延长至8.1个月 ...

Core Viewpoint - Antibody-drug conjugates (ADCs) are considered "biological missiles" in the global innovative drug landscape, attracting significant investment from major pharmaceutical companies due to their precise targeting and potent killing capabilities. The rising R&D costs and complexities have increased the demand for outsourcing services, presenting both challenges and opportunities for Chinese companies [1][3]. Industry Overview - The ADC sector is entering a "golden decade," with 19 ADC drugs approved globally by June 2025 and hundreds more in development. The market demand is expanding, prompting upstream and downstream companies to increase investments. The development of ADCs requires expertise across multiple fields, leading to high R&D costs, averaging between 50 million to 70 million RMB, and potentially reaching nearly 100 million RMB with advanced technologies. The outsourcing rate for ADC development exceeds 70%, significantly higher than the 30%-40% for overall biopharmaceuticals. The global ADC outsourcing market is projected to reach $11 billion by 2030, with a compound annual growth rate of 28.4% [3][9]. Company Profile: BaiO Saite - BaiO Saite, established in 2009, initially entered the market through gene-edited model animals. The company has developed the world's largest humanized mouse library, which has expanded into preclinical services and subsequent antibody development [4][5]. Competitive Advantages - BaiO Saite's core competencies lie in two main business lines: - Gene-edited humanized mice: The company has developed over 4,390 gene-edited animal models, including more than 1,100 humanized models, making it the largest library globally. This library is widely used for evaluating new drug efficacy and safety, enhancing its reputation as an "accelerator" for innovative drug development [5][6]. - RenMice platform's "Thousand Mice, Ten Thousand Antibodies" initiative: This platform supports the discovery of diverse human antibodies, providing foundational molecules for complex drug development. The initiative systematically collects and organizes a vast array of antibody molecules, allowing partners to select directly for further development, significantly reducing the traditional development timeline [6][7]. International Expansion - BaiO Saite has accelerated its international collaborations, signing multiple agreements: - Collaboration with Tubulis: On September 16, BaiO Saite licensed antibodies to the German ADC company Tubulis, which will utilize its proprietary linker and toxin technology for ADC development. This agreement includes upfront payments, milestone payments, and revenue sharing, providing both short-term cash flow and long-term revenue potential [7]. - Third collaboration with Merck: Announced on September 4, this partnership focuses on antibody-conjugated LNP delivery, marking the third collaboration between the two companies, indicating an evolving relationship that extends beyond traditional antibodies [8]. - Joint development with IDEAYA: BaiO Saite is collaborating with IDEAYA Biosciences on bsADC (bispecific antibody-drug conjugates) IDE034, which targets B7-H3 and PTK7, showing significant efficacy in various tumor models. IDEAYA plans to submit an IND application in Q4 2025 [8]. Financial Performance - BaiO Saite's collaborative model has positively impacted its financial results. In the first half of 2025, the company signed 80 new licensing agreements, a 60% increase year-on-year, bringing the total to 280. Revenue grew by 51% to 621 million RMB, with a net profit of 48 million RMB, marking a turnaround from a loss of 50.67 million RMB in the same period last year [9][10]. Strategic Positioning - BaiO Saite is transitioning from an "antibody discovery platform" to a "global R&D infrastructure." The demand for new technologies like ADCs and bispecific antibodies is expanding, and the company aims to provide differentiated source antibody molecules to meet both individual project needs and serve as a foundational platform for industry innovation [10][11]. Conclusion - Over 15 years, BaiO Saite has evolved from a model animal provider to a key player in ADC and global collaborations. In an environment of high R&D costs and lengthy timelines, the company enhances efficiency and fosters international partnerships. As ADCs and "antibody+" technologies accelerate, BaiO Saite's ability to solidify its position as a "Taiwan Semiconductor Manufacturing Company of antibodies" may determine its success in the next industry reshuffle [11].
